SHOE-POLISHING- MACHINE.

Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed March 31,1919. Serial No. 286,456.

Fig. 10 is a fragmentary sectional detail on the line 10-10 of Fig. 9.

Fig. 11 is an end elevation upon a reduced scale looking in thedirection indicated by the arrow 11 in Fig. 5, and looking at theexposed end in Fig. 4, and showing the rollers contracted.

Fig. 12 is a view analogous to Flg. 11

and showing the rollers extended.

Fig. 13 is a longitudinal central section of one of the rollers andtaken on the line I 13-43 of Fig. 14.

Fig. 14 is an end elevation of the roller as seen looking in thedirection indicated by the arrow 14 in Fig. 13.

Fig. 15 is an elevation of one of the roller shafts.

Fig. 16 is an end elevation of the shaft shown in Fig. 15.

The main frame 1 comprises a bottom 2, end pieces 3 and 4 extendingupwardly from the bottom, and a foot support 5 extending upwardly fromthe bottom and connecting the end pieces 3 and 4.

The bottom 2 is mainly flat and has cups 6 pressed downwardly at itscorners and longitudinally extending stiffening ribs 7 presseddownwardly at its sides. The cups 6 form supports to hold the base fromscratching or marring the furniture or object upon which the machine ismounted and holes are formed at the centers of the cups through whichscrews may be inserted to fasten the machine to the support.

The end pieces 3 and 4 have inner plates 8 and 9 and outer plates 10 and11. The inner plates 8 and 9 are formed integral with the ends of-thebottom 2 and are bent upwardly from the ends of the bottom at rightangles and have upturned spacing flanges 12 and 13 around their freeedges. Bearing slots 14 and 15 are formed through the plate 9 parallelwith the bottom 2 and in a line. Similar bearing slots 16 and 17 are,formed through the plate 8011 a level with the bearing slots 14 and 15.The rollers 18 and 19 are mounted between the plates 8 and 9 upon theroller shafts 20 and 21, and the ends of the roller shafts extendthrough the slots 14, 15, 1.6 and 17. The rollers 18 and 19 aresubstantially alike and are constructed as shown in detail in Figs. 13and 14. Each roller comprises a body 22 having rounding tapers 2S and 24extending both ways from the center, flanges 25 and 26 at the outer endsof the tapers, and hubs 27 and 28 outside of the flanges, there being acentral shaft bore 29 extending from end to end. The roller shafts 20and 21 are substantially alike and are shown in detail in Figs. 15 and16, and each shaft comprises a round straight body 30 adapted to fit inthe bore 29, and ends 31 and 32 having flat sides 33 and 34. The ends 31and 32 extend beyond the end faces of the hubs 27 and 28.

An operating shaft 35 is mounted through the centers of the plates 8 and9, said operating shaft having a straight round body 36, flattened ends37 and 38, and a screw threaded portion 39 extending beyond the end 38.Levers 40 and 41 have fiat sided openings to fit non-rotatably upon theends 37 and 38, said levers normally extending both ways equal distancesfrom the shaft. Links 42 and 43 connect the ends of the lever 41 to thecorresponding ends of the shafts 20 and 21. The links 42 and 43 areconnected to the ends of the lever 41 by eyelets 44 and 45 pressed fromthe ends of the lever 41 and extending through openings in the ends ofthe links 42 and 43, and the outer ends of the links 42 and 43 have flatsided openings fitting nonrotatably upon the ends 31 and 32 of theshafts 20 and 21, so as to hold the shafts from rotating, and so thatthe rollers 18 and 19 will rotate freely on the shafts. In a like mannera lever 46 is fixed upon the end 37, and links 47 and 48 connect theends of the lever 46 to the ends 31 of the shafts 20 and 21.

Tang openings 49, 50 and 51 are formed through the plate 9 just abovethe bottom 2, and similar tang openings are formed through the plate 8just above the bottom 2. In a like manner tang openings 52 and 53 areformed through the upper edge of the plate 9 just inside of the flange13, and similar tang openings are formed through the plate 8. Theopenings 49, 50, 51, 52 and 53 serve to mount the plates 10 and 11.Tangs 54 and 55 extend from the plates 10 and 11 through the openings49, 50, 51, 52 and 53, and the inner ends of the tangs are bent to holdthe plates in place, so that the plates 10 and 11 cover the levers 40and 41, the links 42 and 43, and 47 and 48, and the other parts outsideof the plates 8 and 9.

An indicator arm 56 has a fiat sided open ing fitting non-rotatably uponthe screw 39,

and a handle 57 extending outwardly from the outer end of the arm. Theindicator arm 56 is parallel with the levers 40 and 41. Spacing washers58 and 59 are placed upon the ends 37 and 38 between the plates 8 and 9and the levers 40 and 41. A lock nut 60 is screwed upon the end 39against the indicator arm 56, so that when the lock nut 60 is loosenedthe handle 57 may be manipulated to move the rollers 18 and 19 to orfrom each other, and then when the rollers have been moved to thedesired locations the lock nut 60 may be tightened to hold the rollershafts 20 and 21 rigidly in their adjusted positions, and at the sametime allow the rollers to run freely upon the shafts. v

The foot support 5 is formed of sheet metaland comprises a central topplate 61, side plates 62 and 63 extending downwardly and inwardly fromthe side edges of the top plate 61 and resting upon the bottom 2, therebeing tangs 64 and 65 extending from the ends of the side plates 62 and63 through the plates 8 and 9 and riveted, and tangs 66 and 67 extendingdownwardly from the side plates 62 and 63 through the bottom 2 and bentlaterally. A heel depression 68 is formed in the top plate 61.

In the practical operation the polishing cloth 69 cut to the desiredlength and width and having handles 70 at its ends is passed under therollers 18 and 19 and over the foot support 5. The shoe to be polishedis placed upon the foot support 5 under the central portion 71 of thecloth, the handles 70 are grasped and the cloth drawn back and forthfirst with one hand and then with the other. The taper of the rollersprovides a traveling motion for the cloth, so that as the cloth isreciprocated endwise it will move back and forth laterally of the clothand endwise of the rollers. The flanges 25 and 26 serve to hold thecloth from running beyond the ends of the rollers.

In Fig. 1 I have shown the operation of polishing the toe of a shoe 72.In Fig. 2 I have shown the operation of polishing the lower part of theinstep by placing the shoe centrally upon the support 5 and tipping thefoot first one way and then the other. In Fig. 3 I have shown theoperation of polishing the upper part of the instep and the sides of theankle by placing the heel 73 in the heel depression 68 and tipping thefoot first one way and then the other.

Various changes may be made without departing from the spirit of myinvention as claimed.

I claim:

1. In a shoe polishing machine a frame having a bottom, end piecesextending upwardly from the bottom, a foot support connecting the endpieces above the bottom, and rollers mounted in the end pieces above thebottom one on each side of the foot support, said rollers being taperedboth ways from the center.
